Description

Technical Field

[0001] This utility model belongs to the technical field of boiler water-cooled wall tube panels, specifically relating to a water-cooled wall tube panel cutting device. Background Technology

[0002] Water-cooled walls are the main heat-receiving part of a boiler. They consist of several rows of steel tubes distributed around the boiler furnace. The tube panels can be prefabricated in bulk at the factory for easy on-site installation. Traditional cutting methods use flame cutting, which has a large heat-affected zone. Therefore, it requires highly skilled operators who need to avoid thermal deformation to ensure the accuracy and effectiveness of the cut. It also produces a large amount of molten slag, which is prone to oxidation. In addition, the traditional method involves using a crane to place the tube panel in the pre-operation area, and then the operator performs micro-manipulation to meet the cutting requirements. However, water-cooled wall tube panels are heavy, making manual movement and positioning difficult, resulting in high labor intensity. Furthermore, the limited space for cutting a single tube is time-consuming and labor-intensive, making it difficult to guarantee the accuracy and consistency of the cut, and increasing the workload of subsequent processing. Utility Model Content

[0003] This invention provides a water-cooled wall tube panel cutting device to overcome existing technologies. This invention reduces the workload of subsequent processing, enabling products to reach high quality standards after initial cutting, avoiding defects prone to occur in flame cutting, improving product quality, and reducing labor intensity.

[0004] A water-cooled wall panel cutting device includes a base, a lifting mechanism, a moving trolley, a roller assembly, a positioning mechanism, and a cutting machine. The roller assembly is mounted on the base and can be driven by a power source for conveying the water-cooled wall panel. The positioning mechanism is mounted on the base for positioning the moving path of the water-cooled wall panel. The cutting machine is mounted on the moving trolley for cutting the water-cooled wall panel. The moving trolley is slidably mounted on the lifting mechanism for controlling the linear movement of the cutting machine, the direction of movement of the cutting machine being perpendicular to the axis of the roller assembly. The lifting mechanism supports the moving trolley and fixes or releases the water-cooled wall panel.

[0005] Furthermore, the lifting mechanism includes a platform and lifting cylinders; the lifting cylinders have two symmetrically arranged along the width direction of the base, the movable end of the lifting cylinder is installed on the bottom surface of the platform, the cylinder body of the lifting cylinder is fixed, and the moving trolley is slidably set on the platform.

[0006] Furthermore, the roller assembly includes rollers, sprockets, and chains; multiple rollers are arranged side by side along the length of the base, the rollers are rotatably mounted on the base, and one end of each roller has two sprockets coaxially connected, with adjacent rollers driven by chains meshing with the sprockets.

[0007] Furthermore, the power source includes a geared motor and a chain drive mechanism; the geared motor is mounted on the base, and the output end of the geared motor is connected to any one of the rollers through the chain drive mechanism.

[0008] Furthermore, the positioning mechanism is a double roller frame, installed on one side of the base, with the positioning roller axis arranged vertically and used to laterally support the water-cooled wall tube panel.

[0009] The advantages of this utility model compared to the prior art are:

[0010] This invention changes the traditional flame cutting method. The cutting device of this invention is a semi-automatic structure, avoiding the defects that easily occur in flame cutting, such as uneven cut surfaces, slag, and damage to the base material. The cutting speed is 2-3 times that of traditional flame cutting. In the production process, rapid cutting can significantly shorten the production cycle.

[0018] The embodiments of the technical solutions of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise stated, the technical or scientific terms used in this application have the ordinary meanings understood by those skilled in the art.

[0019] Example 1, Reference Figures 1-6The water-cooled wall tube panel cutting device provided in this embodiment includes a base 1, a roller assembly 2, a positioning mechanism 3, a lifting mechanism 4, a moving trolley 5, a cutting machine 6, and a power source 7;

[0020] Reference Figure 2 The roller assembly 2 is mounted on the base 1 and is used to support and transport water-cooled wall tube panels. The roller assembly includes rollers 21, sprockets and chains 22. There are multiple rollers 21 arranged side by side along the length of the base 1. Each roller 21 is rotatably mounted on the base 1. One end of each roller 21 has two sprockets coaxially connected. Adjacent rollers are driven by chains 22 that mesh with the sprockets. Any roller 21 can be driven by a power source 7. Under the transmission of the chain, multiple rollers 21 can rotate synchronously.

[0021] Furthermore, referring to Figure 3 The power source 7 includes a geared motor 71 and a chain drive mechanism; the geared motor 71 is mounted on the base, and the output end of the geared motor 71 is connected to any one of the rollers 21 through the chain drive mechanism. The synchronous rotation of multiple rollers 21 is achieved through a two-stage chain drive mechanism, which achieves the purpose of low speed, multi-axis, wear resistance, long transmission path and long service life.

[0022] Positioning mechanism 3 is installed on base 1, as shown in the figure. Figure 1 The positioning mechanism is a double positioning roller frame, with two positioning rollers 31 on each roller frame and located on either side of the base 1. The positioning rollers 31 are rotatably mounted on the roller frame. The axes of the two positioning rollers 31 are arranged vertically and perpendicular to the horizontal axis of the roller 21, so as to laterally support the water-cooled wall tube screen, realize the positioning of the water-cooled wall tube screen to move along a predetermined moving route, prevent deviation, and achieve the guiding function.

[0023] Reference Figure 4 The lifting mechanism 4 can be independently installed on the ground or fixedly connected to the base. The lifting mechanism 4 includes a platform 41 and a lifting cylinder 42. There are two lifting cylinders 42 symmetrically arranged along the width direction of the base 1, which are installed on the ground. The movable rod of the lifting cylinder 42 is installed on the bottom surface of the platform 41. The cylinder body of the lifting cylinder 42 is fixed. The moving trolley 5 is slidably installed on the platform 41. When the water-cooled wall tube screen is transported to the vicinity of the platform 41, the platform 41 has been lifted by the lifting cylinder 42. The water-cooled wall tube screen passes through the space under the platform 41 and stops moving after reaching the cutting position. The action of the lifting cylinder 42 causes the platform 41 to descend until the water-cooled wall tube screen is clamped and fixed. At this time, the lifting cylinder 42 stops working. After the water-cooled wall tube screen is cut, the action of the lifting cylinder 42 lifts the platform 41 to release the water-cooled wall tube screen, which facilitates the operation of the subsequent work of the water-cooled wall tube screen. The lifting mechanism 4 realizes the function of supporting the moving trolley 5 and fixing or releasing the water-cooled wall tube screen.

[0024] The mobile trolley 5 is slidably mounted on the lifting mechanism 4, as shown in the reference. Figure 5 The cutting machine 6 is installed on the mobile trolley 5 and is used to cut the water-cooled wall tube panel. The upper surface of the platform 41 has a track 410 to guide the movement of the mobile trolley. The mounting base of the cutting machine 6 has guide wheels 61 that move along the track 410. Through the interaction between the track 410 and the guide wheels 61, the linear movement of the cutting machine 6 is controlled. The movement direction of the cutting machine 6 is perpendicular to the axis of the roller 21, ensuring that the transported water-cooled wall tube panel is accurately cut and guaranteeing the accuracy and consistency of the cutting position.

[0025] To further ensure the accurate movement of the cutting machine 6 and the cutting of the water-cooled wall tube panel, refer to Figure 6 The platform 41 has a positioning groove 411 on its upper surface to prevent lateral displacement. The positioning groove 411 and the track 410 are parallel in length direction. The mounting base of the cutting machine 6 has a slider 62 that moves along the positioning groove 411. The cutting machine 6 is preferably an abrasive wheel cutting machine.

[0026] The advantages of this embodiment are: 1. Fast cutting speed, shortened production cycle, and improved production efficiency.

[0027] 2. The short cutting allowance and smooth cutting end face reduce the workload of subsequent processing, enabling the product to reach a high quality standard after the initial cutting, saving materials and processing costs.

[0028] 3. Reduced chamfering work, improving production efficiency.

[0029] 4. Reduce tool consumption, decrease tool replacement frequency, and lower manufacturing costs.

[0030] 5. It avoids the defects that are prone to occur in flame cutting, such as uneven cutting surfaces, slag, and damage to the base material, thereby improving product quality.

[0031] 6. This cutting mode requires no technical skills from the operator. By following the operating procedures and using the equipment, high-quality cutting can be achieved, reducing reliance on human expertise and decreasing personnel training costs and labor intensity.

[0032] Example 2: Based on the scheme of Example 1, the specific workflow is as follows:

[0033] (1) Raise the cutting machine 6 and place the workpiece (water-cooled wall tube panel) on the roller 21;

[0034] (2) The side of the workpiece is in close contact with the positioning roller 31;

[0035] (3) Start the power source 7. The workpiece is driven by the roller assembly 2 to move to the near-raised platform 41, and then passes through the space under the platform 41 to reach the cutting position. The workpiece stops moving, and the platform 41 is driven down by the lifting cylinder 42 until the workpiece is clamped and fixed.

[0036] (4) Lower the cutting machine 6 and move the trolley 5 to perform the cutting;

[0037] (5) After cutting is completed, the cutting machine 6 is raised, the platform 41 is lifted by the lifting cylinder 42, the workpiece is released, and the workpiece is retracted to complete the cutting. The application of the cutting mode in this embodiment brings significant improvements to enterprises in terms of production efficiency, product quality and cost control.

[0038] This application has been disclosed above with preferred embodiments, but it is not intended to limit this application. Any person skilled in the art can make some changes or modifications to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the technical solution of this application, and all such modifications and modifications are within the scope of the technical solution of this application.
